T 0 all whom it may concern:

Be it known that I, Hnowre Scrrwrnenn, KIPP, a citizen of the German Republic, and residing at Hanover, Germany, have invented certain new and useful Improvements in Closures for Glasses for Preserved Fruits and the like, of whichthe following is a specification. I 1 v with the known glasses containing p re-' served fruits and the like, the lifting of the lid from the glass, for the purpose of-opening the latter, is rather difficult owingto the vacuum formed-in the-freev upper part of the interior of the glass. The glasses can mostlyrbe opened with great difficulty only, while they frequently break and particularly the tightening rubber washer between glass and lid becomes so much damaged.

- that it cannot more be'used afresh. Owing to the high costs of material, said drawbacks.

areof essential economical importance.

The present invention provides simple means by which said drawbacks are effectively overcome. For this purpose, the lid-fof-the glass has a depression, which is preferably centrally located'therein and which is tapered, that is wider at the top than at the bottom. and which through a small orifice in" its bottom is in communication with the interior of the glass. Said depression serves for. thereception of a correspondingly. shaped soft-rub ber stopper therein, said stopper having either a narrow central. slot-opening therein or being two-parted in its length and form- .ing said slot-opening between said two parts. Said stopper is put in said depression of the lid during the boiling of the glasses with their contents therein and with the lids thereon, whereby the stopper is firmly sucked into said depression by the formation of the vacuum mentioned and the small orifice in the bottom of said depression is thus airtightly closed while at the same time also the narrow central slot-opening in the stop per is closed by the latter being contracted, or the two longitudinal halves of the stopper are firmly pressed upon one another so as to form practically one piece, as the case may be.

To open the glass, it is only necessary to spread the contracted stopper apart to open its narrow central slot-opening, so that at mospheric air is vadmitted to the interior of the glass through said slot opening and through the small orifice in the bottomof the depression in the lid. Preferably, for this purpose, .a small implement is used which consists of an annularhandle and. a

bladelike'member thereon, in which a-lon-.

gitudinal central bore witha lateral port is provided in such a way that, when the blade is pushed-into the contractednarrow central slot-opening of the stopper, or between the two parts of the same, a communication is created through the bore insaidimplement between th'e interior of the glass and the outer air, whereby the latter is admitted to thezvacuum in the glass, the latter is neutralized, and the-lid can be easily lifted from the; glass without damage to the same or. to the tightening rubber washerbetween glass and lid. 1 7

. ,The arrangement may also be such that a flat pin of any suitableinaterial is put in the fnarrow' slotbpening of the stopper, before pin; returning after its. liberation -automati-- Cally to its initial position: owing to the elasticity of thevmaterial" of the stopper,

, %Theannexed. drawing shows :variousaappropriate constructional forms of the subject matter of thepresent invention.

Referring to Figs.- 1 to eincl. :3 desig nates the glass with an upper flange 2 on which the lid a is put by means of an intermediaryrubber washer 1-, as known in the art. 5 design-ates the tapered depressionin said lid having a small orifice 6 in its bottom, through which it is in communication with the interiorof the glass. 7 designates the sort-rubber stopper with a narrow central slot-opening 8therein. 9 designates the implement for opening the stop er after its contraction as afore-des'c'ribed. or this urpose-, the im lement is with its bladeits upper part-th-at the flat pin 17, when iiilike member pushed through the'lia'r'row central slot-opening 8 until a communication through the central bore 10 and its lateral port 11 is created between the interior of the glass and the outer air, with the result described above. "lathe example shown in Figs. 5 to 9 incl, the de 'ares'sion 12' of the lid 13 extends somewhat d'ee erand is so widened at serted theslot 15' ofthe stopper 16, lies with its handle 14 within said widened up per part in such a way that it can be caught by hand: for turning-the pin 17 for them:- pose aforementionedy i As" shown in Figs. 10'and'11, the stopper may consist of two longitudinal halves 18 and19, 'in which indentations 20 for the in are provided.

or 1 2 (Fig. 5), which labelni-ay at the same'tim'e serve for inscriptions ind1- parts, and 'Figqll is a plan cating the date of filling,,or;the nature of the contents in the glasses, or the'like. The glasses can be put above each other, as the upper surface of the lid is completely smooth. c

The depression 5, or 12, in the lid is cupshaped at its bottom, whereby a small free space is left between the latter and the lower end of the stopper. v i

A great advantage of the improved arrangement lies in the fact that the contents of the glass cannot come in contact with the rubber stopper in the depression 'of the lid.

In a'clo'sure for glasses for preserved fruits and the like, in combination, a lid having atape'r'ed depression therein with a small orifice in its cup-shaped bottom, a soft-ii'ubber' stopper of corresponding forms. tion in said depression having'a narrowcei'itral slot-opening therein, and an opener for an eventual insertion in the slot-opening of said stopper ionsisting of an annular handle and a blade-like member" having a central bore with a lateral port thereimsubstanti'ally asan'd for the purpose set forth.

2.- In a ol'osure for glasses for preserved fruits and the like, in combination, a lid having a tapered depression therein with a small orifice in its bottom, a soft-rubber stopper of corre ponding formation in said depressionhaving "a narrow central slot HEDWIG'SGHWIEGER, KIP'P; v
